Ob-Gyn questions? Ask a gynecologist online.
the hormonal cycle is a very sensitive precedure which can be influenced by many factors. Even stress or climate changes can play a role, also the supplement you took. An ovarian cyst could be another reason for the delay of your period. At this time the test result is very reliable so you can exclude pregnancy for sure. I would recommend an examination by your OB/GYN if bleeding doesn´t occur during the next 5 days. It can be provoked then by hormonal medication.
